Baldur's Gate 3: Underdark or Mountain Pass Choice Guide

This guide will help players decide whether to use the Underdark or Mountain Pass to reach the Moonrise Towers in Baldur's Gate 3.

In order to reach the Moonrise Towers in Baldur's Gate 3, players must traverse the Mountain Pass or Underdark. While fans should feel free to pick either of these routes, some players may want more information about the options before they proceed. This guide is here to provide that information, and it will help fans decide whether they should travel across the Mountain Pass or pass through the Underdark in Baldur's Gate 3.

It is first important to establish that it is possible to explore both the Mountain Pass and Underdark in Baldur's Gate 3, and players are advised to do exactly that. Indeed, there is interesting content to experience and powerful rewards to earn in both areas, and here is a recommended order for fans to use:

If a player is not interested in exploring both the Underdark and the Mountain Pass in a single playthrough then they may want to base their decision on the scale of the two areas. Indeed, fans that are looking for an expansive route to the Moonrise Towers should consider passing through the Underdark, while players that want something more compact should set their sights on the Mountain Pass.

Alternatively, fans could allow their companion's quests to inform their decision. For example, players that want to pursue Lae'zel's quest should take the Mountain Pass, as that is where the Githyanki Creche is located, while fans that want to pursue Shadowheart's quest should use the Underdark. Again, all of this can be experienced in one playthrough by exploring both areas before advancing into the Shadow-Crused Lands, which is sure to be exciting news to some players.

Finally, Baldur's Gate 3 players may want to consider difficulty when deciding between the Underdark and the Mountain Pass. More specifically, fans that are looking for a challenge may find the Underdark more exciting, while players that would prefer an easier journey may be happier with the Mountain Pass. That said, fans that only explore the above ground route may find themselves slightly under-leveled upon entering Act 2, which is yet another reason to take the time to visit both areas.

Baldur's Gate 3 is available now on PC. A PS5 version releases on September 6.
